Phivolcs records two phreatic eruptions on Sunday morning, with the agency raising Alert Level 2 over Mayon due to increasing unrest.

The National Disaster Risk Reduction and Coordinating Council (NDRRMC) says 919 families have sought shelter at four public schools in Camalig and Guinobatan, Albay.

By 8 p.m., Phivolcs raises Alert Level 3 over the volcano as the beginnings of lava flow are spotted, warning of an "increased tendency toward eruption" that may occur within days or weeks.

The agency also recommends extending the PDZ to include a 7-kilometer-radius Extended Danger Zone (EDZ) to the south of the volcano due to the dangers of rockfall, landslides and hazardous volcanic flows.

Albay's Provincial Disaster Risk Reduction and Management Office says more than 4,300 residents within a 7-kilometer radius of the volcano have evacuated and sought shelter in schools. Thus, classes from kinder to senior high school in all public and private schools in the province have been suspended.

The provincial government declares a state of calamity over Albay, which allows the local government to fully mobilize all agencies and resources to respond to emergencies, as Mayon threatens a hazardous eruption.

At least nine volcanic earthquakes and 75 lava collapses are recorded on Tuesday, resulting in rockfall.

Plumes of ash as high as two kilometers eventually fall on barangays in Camalig, Guinobatan, and Polangui.

Disaster officials say as of 5 p.m., there are more than 34,000 evacuees from 25 affected barangays in the municipalities and cities of Camalig, Guinobatan, Ligao City, Daraga, Tabaco City, and Malilipot.

Meanwhile, in the provincial capital Legazpi City, Mayor Noel Rosal orders a preemptive evacuation in five barangays inside the 7-kilometer EDZ south of Mayon.

Government agencies have extended nearly ₱33 million in assistance to the residents.

After returning from his trip to India, President Rodrigo Duterte says he may visit Albay in one to two days, despite the difficult conditions for aircraft.

"It's the wind current you have to worry about because it will bring the ashes to where you are," he said. "But if it's safe to go there, and even if it's not, you give me the space to land, if I'm cleared, I'll go there, in about one or two days."
